 \fBvwprintw\fR is marked TO BE WITHDRAWN, and is to be replaced by a function

+.bP
 The Single Unix Specification, Version 2 states that
 \fBvw_printw\fR  is preferred to \fBvwprintw\fR since the latter requires
 including \fB<varargs.h>\fR, which
 cannot be used in the same file as \fB<stdarg.h>\fR.
